时序数据库(Time-Series Database)是一种专门用于存储和查询带有时间戳的数据的数据库系统。时序数据通常具有以下特点: 以时间为中心:每条数据记录都包含一个时间戳。 仅追加:数据主要是追加操作,很少进行修改或删除。 高写入并发:数据写入频率高,且写入后很少进行修改。 2. 介绍PostgreSQL作为时序数据库的适用性 Post...

Why Use Citus To Scale Out Postgres? One Word: Performance. Citus distributes and parallelizes Postgres workloads—and is often used as a system of record for SaaS apps and microservices, and as a system of engagement for analytics dashboards and time series data. Often, teams use the Citus...
range partitioning to partition your tables by time ranges (super useful for time series data) and then—assuming your application needs more cpu and memory than you can get on a single node—you can also use Citus database sharding to distribute sharded partitions across a multi-node clust...
Citus Con 的 Burak Velioglu 会议演讲视频:Postgres 活动。 摘要:大规模管理时序数据可能是一项挑战。 PostgreSQL 提供了许多强大的数据处理功能,例如索引、COPY 和 SQL,但数据量大,时序数据不断增多的性质可能会导致数据库随时间推移而变慢。 Burak Velioglu 是 Microsoft 在 Citus 开放源代码 工程团队工...
